Appl. No.:

6/568701

Inventors:

David A. Nuttle - Raleigh NC

International Classification:

G21F 900

US Classification:

405128

Abstract:

This invention is a system for field disposal of human feces through the use of composting containers that prevent the spread of intestinal bacteria, including virulent pathogens, which otherwise would occur when wilderness visitors practice shallow burial of feces. This is accomplished by providing biodegradable containers and following a pre-set method of disposal.

Appl. No.:

6/628481

Inventors:

David A. Nuttle - Youngsville NC

International Classification:

C02F 312
C02F 900

US Classification:

2105322

Abstract:

This invention is a sanitary disposal system for human waste and organic garbage by aerobic composting combined with solar evaporative distillation for greywater. The aerobic composting reduces waste volume by ninety percent leaving water, carbon dioxide and a harmless but fertile ash by-product. Except for urine, the system essentially operates dry. No chemicals, septic system, or sewage treatment plant is required. There is no odor and no polluting discharged during operation. A nonsoiling toilet seat is provided so a dry toilet bowl may be used without the usual problems of cleaning. Insects are prevented from entering or leaving the system which is constantly aerated to assure that the composting process does not convert to anaerobic. The greywater system further enhances pollution control. This includes solar evaporative distillation to separate out solids which can be disposed of in a sanitary dump while the reclaimed water can be used for non-household purposes.

Appl. No.:

6/791989

Inventors:

David A. Nuttle - Youngsville NC

International Classification:

A01M 2904

US Classification:

43 2

Abstract:

This invention is a combination of visual and aural devices to create panic in selected bird species. This is accomplished in part through a body simulating a Tiger Cat which is weathervane mounted. The body includes bright orange stripes and has predatory eyes. Streamers depicting paniced birds are attached to the tiger's tail and an internal wind driven flute produces a variety of the noises. Additionally, reflectors are used on a propeller to simulate light reflection from a gun barrel. Further, random or scheduled explosions from an automatic acetylene exploder and bird warning and distress calls are broadcast over loud speakers for the species of birds being repelled.
